[IMP] rating: don't call compute method directly

The correct way to trigger a recomputation of a field is not
to call directly the compute method. The ORM offers mecanism
to do it: we have to flag the field as "recompute to do" and
then call `recompute` method (availble on every models). This
one will call the recompute method of all fields marked as
"to recompute".

This will optimize the performance by doing recomputation in
batch.
